Adds a structured set of 11 query scenarios covering the main catalog database access patterns: paginated listings, counts, facets, entity lookups, full-text search, ancestry traversal, stitching reference counts, and orphan detection. Each scenario documents the SQL, what a healthy plan looks like, and what anti-patterns to watch for. The baseline records execution times and plan shapes from the staging database (545K entities, 13.8M search rows). This is intended to be run by humans or AI agents before and after database-affecting changes to detect performance regressions. It lives alongside the existing performance tests.
